The second chapter of the film focuses on the policeman, Bradley Cooper. Avery and Luke both hold a sort of intensity that makes you believe in them, to gun for them. It's in the gaze, in the furrowed brow and nonchalant expression, juxtaposed with the eyes. It's his quest to better the world, but meanwhile losing a relationship with his son. It's guilt, mixed with hope.
The final chapter meets the two sons – Avery and Luke's – and comes with a sense of loss and fulfilment. Making for a film that provokes, saddens and most importantly, engages with a feeling that we can't ever control every aspect of our lives. That emotions can rule even the strongest of minds, and that the physical body rules above all and makes for our physical existence. So, switch this round: where we take our body, can free the mind and in turn, make our emotions even more visceral and real.
